Do **NOT** sign up to this one and sign-up at https://www.meetup.com/columbusjs/events/313386504/ ======================================= A hand tracker gives you joints, not a gesture. This talk shows how you get from raw joints to a "thumbs-up" in Unity: the pipeline that cleans up the data, how a gesture becomes a few 0-to-1 values within tolerance, and why orientation matters as much as finger shape. Includes a live demo of tuning gesture thresholds. Food and drinks will be available. **LOCATION:** 6515 Longshore Loop, Suite 300, Dublin, OH 43017 **FREE PARKING:** 6725 Longshore Street, Dublin, OH 43017

Bring your Raspberry Pi, Arduino, microcontroller, or any other electronic project and join fellow electronics makers for a night of creativity and collaboration! This session is open forum to share your current projects—whether complete or in progress, it’s all interesting! Whether you’re deep into embedded systems, exploring new ideas, or just getting started, you’ll find a welcoming space to collaborate, share, and get inspired. **New to electronics or curious about tinkering?** You’re absolutely welcome. If you’re a beginner and want to experiment, I’ll have a couple of starter kits available so you can try things out—whether that’s blinking your first LED, putting something on a display, or experimenting with simple sensors. No pressure and no experience required—just an interest in learning and building. While we continue to pursue a more permanent venue for this Meetup, we’ll be using public library facilities based on availability.

Join us as we get together for a CAPA Summer Movie event to see the romantic, funny, heartwarming, feel-good classic, PRETTY WOMAN! Julia Roberts and Richard Gere star in this modern-day fairy-tale romance! Here’s a description, trailer and plan for this event: DESCRIPTION: A wealthy corporate raider hires a Hollywood escort as his date for a week of high-society business events. But what starts as a business transaction blossoms into genuine love, challenging both of their lives and leading to an unexpected romance. The film is directed by Garry Marshall and stars Richard Gere, Julia Roberts, Héctor Elizondo, Ralph Bellamy (in his final performance), Laura San Giacomo and Jason Alexander.

Critics praise Julia Roberts’ star-making performance, the undeniable chemistry between her and Richard Gere, and its warm, funny feel-good story about kindness, self-worth and transformation! The film’s “intelligence and wit,” “first-class performances” and “sharp, funny script” have made Pretty Woman a classic and truly “something special!” THE OHIO THEATRE: The Ohio Theatre is located at 39 E.

The breathtaking details (including the 21-foot-high chandelier!) of its opulent, Spanish-Baroque architecture make any night at the Ohio Theater an event to remember!

*We'll update this with the specific topic(s) once they're set for the month.* A relaxed, community-driven Unity GameDev meetup. No strict agenda — just developers getting together to talk shop, share projects, and exchange ideas. Some topics that may come up (based on attendee interest): * Frame Debugger & performance tooling * Addressables & additive scene workflows * Input System, localization, responsive UI * AI integration approaches * DevOps & LiveOps experiences * Full lifecycle: idea → cross-platform publishing * Favorite Asset Store tools and hidden gems * Weird Unity quirks we've all run into Nothing is locked in. Bring a project if you'd like, bring a question, bring a lesson learned — or just come hang out and meet other developers. All skill levels welcome. Food and drinks provided.

Most people use LLMs by feel: ask a question, read the answer, decide whether it “seems good,” and move on. That works for casual use. It does not work when you are building software, automating workflows, writing important documents, or relying on AI for anything that needs to be repeatable. In this talk, we’ll look at how to improve and evaluate the inputs and outputs of LLMs using practical measurement techniques. We’ll cover how prompt changes affect results, how to compare outputs, how to build simple evaluation sets, and how math-based methods like similarity scoring can help you move beyond guesswork. This will be beginner-friendly, so even if you don't know anything about AI, you should get something out of it. However, this will be a little more technical than our intro talks. You do not need to be an AI researcher, but programmers and technically curious attendees will get a lot out of it. We’ll cover: * Why “it looks good” is not enough * How to improve prompts by changing the input, context, and constraints * How to compare LLM outputs more systematically * Basic evaluation techniques for accuracy, consistency, and usefulness * How embeddings, cosine similarity, and scoring can help evaluate results * Where automated evaluation works — and where humans still need to stay in the loop By the end, you’ll have a practical mental model for treating LLMs less like magic and more like systems you can test, measure, and improve. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.

You can sleep in on the Sesquicentennial (observed), we’re shifting to the following Friday. But join the local UX community for a chat and some biscuits to catch up. If you were in CA for Figma Config, tell us all the lines and you can tell me how I can animate an SVG without coding it by hand, and why I’d even want to. Thanks to the team at Nationwide of supporting the group.
